US Patent:

6560967, May 13, 2003

Filed:

May 29, 1998

Appl. No.:

09/086968

Inventors:

Jeffrey Mark Cohen - Hebron CT 06248
Nancy Mary Rey - Glastonbury CT 06033
Gonzalo J. Rey - Glastonbury CT 06033
Clas A. Jacobson - Tolland CT 06084

International Classification:

F02C 7232

US Classification:

60776, 60 39281, 60725, 60737

Abstract:

An apparatus for use in a system having a gas fuel supply and a combustor includes a fuel actuator, a controller; and a premixer. The controller generates a command signal indicative of actuation sought from the fuel actuator. The actuator receives gas fuel from the liquid fuel supply and provides liquid fuel at a modulated rate of flow in response to the command signal. The premixer receives the fuel from the actuator, mixes the fuel with air, and provides the mixture to the combustor.

International Classification:

F02K 112

US Classification:

602263, 60232, 244219

Abstract:

A gas turbine engine includes a variable area nozzle having a plurality of flaps. The flaps are actuated by a plurality of actuating mechanisms driven by shape memory alloy (SMA) actuators to vary fan exist nozzle area. The SMA actuator has a deformed shape in its martensitic state and a parent shape in its austenitic state. The SMA actuator is heated to transform from martensitic state to austenitic state generating a force output to actuate the flaps. The variable area nozzle also includes a plurality of return mechanisms deforming the SMA actuator when the SMA actuator is in its martensitic state.

International Classification:

F01B029/10
F02G001/04

US Classification:

060527000

Abstract:

A plurality of individual shape memory alloy (SMA) wires are formed into a SMA bundle to increase force output therefrom. The SMA bundle has a parent shape and a deformed shape. The SMA bundle in the deformed shape resumes its parent shape once the SMA bundle is heated to generate increased force output. The SMA wires can be configured into strands, ropes, arrays or other shapes. The SMA material is also used in a variety of actuators for generating substantially continuous motion.
